The swimming of aquatic animals and flying of insects and birds have fascinated physicists
and biologists for more than a century. In this regard, great efforts have been made to …

In the recent decades, the design and development of biomimetic micro air vehicles have
gained increased interest by the global scientific and engineering communities. This has …

This study integrates high-speed photogrammetry, 3D surface reconstruction, and
computational fluid dynamics to explore a dragonfly (Erythemis Simplicicollis) in free flight …

The flapping wings or fins in an in-line arrangement are a common scene in flocks and
schools, as well as flying creatures with multiple pairs of wings, eg, dragonflies …

Direct numerical simulations have been performed to analyze how three-dimensional effects
influence the performance of wings in tandem configuration undergoing a two-dimensional …

In nature, the phenomenon of cluster movements of fish, birds, and insects is universal,
which constantly inspires people to explore its advantages. In this study, the aerodynamic …

We present a quantitative characterization of the unsteady aerodynamic features of a live,
free-flying dragonfly under a well-established flight condition. In particular, our investigations …

In nature, insects with their forewings and hindwings undergoing small-gap flapping motion
experience strong aerodynamic interaction. Conventional studies mainly focus on the …

We reveal the hindwing kinematics of a damselfly that are optimal for the thrust efficiency,
which is a major concern of a bio-inspired micro-aerial vehicle. The parameters of the …

The effects of the phase difference between fore-and hindwings are experimentally
investigated on the aerodynamic force, aerodynamic efficiency, and longitudinal control …
